or emit a continuous beep, indicating a closed, healthy loop.
If it appears in , the device driver is missing, corrupted, or disabled.
In 90% of the cases I saw (including mine), the issue was a corrupted temporary file that refuses to overwrite itself. 3mp31702 fix fixed
Slide the new 3MP31702 into the same position. It must be "fixed" tightly against the motor to accurately sense temperature.
A surprisingly common issue is : the connecting lead of the 3MP31702 breaks off because of strong vibrations, especially in older machines where the motor impeller has become unbalanced. The broken lead or cracked solder joint makes the motor appear dead, even though the bimetallic switch itself may still be functional. or emit a continuous beep, indicating a closed, healthy loop
If the failure is purely mechanical (a broken lead or cracked solder joint) and the bimetallic element itself is still intact, you can attempt a simple repair. Using a fine‑tip soldering iron, carefully reattach the broken lead. A skilled repairer on the Repair Café forum notes that “with a good soldering iron, you can improvise a new pin.” They recommend generous soldering of the case and cover to achieve a connection that is stronger than the original.
Some specific versions of the 3MP series may require a manual reset for higher safety, though these are less common in standard consumer appliances. Replacement: Slide the new 3MP31702 into the same position
The issue is often a symptom of environmental wear on a critical component. By following the systematic approach of inspecting for mechanical fatigue or electrical failure, cleaning or replacing the part, and ensuring correct torque/sealing, you can ensure a lasting, reliable repair.
